and Cellulosic Material from Nuts, of which the following is aspecification. Our invention relates to a method or process for;extracting and recovering oils .or

fats from nutsand their shells and for obtaining a residue of cellulosicmaterial in suitable'condition for conversion into glucose.

We take cocoa-nuts, cohoune nuts, coquito nuts, coyol nuts, corozo nuts,or nuts of similar kind, many of such having a shell of veryconsiderable thickness. The nuts chiefly used have a shell and sometimesfiber of from 80 to 90 per cent. of the whole so that the kernel is acomparatively small portionof such nuts. We take such nuts, shell, I

boiled liquid is run ofl' or otherwise sepain one process. Both'theneutralizing and de-colorizing treatment may, convemently extend over aper1o' d of from 2 to 6 hours. The clear syrupy hquid obtained after theboiling is finally further boiled or ev'aporated to produce glucoseliquor, which we may market, or we'may treat such liquid to obtaincrystals.

The amount of the re-agents used and the length of time the masses orliquors are subected to treatment and heat depends largely on thecharacter of the nuts and varies according to the thickness and hardnessof the shells and fibers.

By our invention we can economically extract oil from nuts including theshells and fiber, kernel altogether, as gathered, or fibers (or in casesuch are marketed from plant. For example we add 1 to 7 per cent.

of benzin. The mass is subjected to heat.

This treatment with benzin may extend over a period oil from. 2 to 6hours, the oil extracted by treatment with benzin or like spirit beingrun off. In this manner the oils from the entire ground nuts, or fromthe shells, fiber and kernels separately, is obtained, and such oil maybe submitted to any desired further treatment. The residue of shell orfiber and kernel (mostly ground shell) is then treated in a pan or otherreceptacle with mineral acid as for example sulfuric acid and water andis boiled by steam heat or. otherwise. We use from 1 to 7 per cent. ofacid and a sufliciency of water and we boil. from 2 .to 6 hours as foundnecessary. Following this treatment, the

The herein-described process for ob taining oilfrom cohoune nuts, coquito nuts, coyol nuts, corozo nuts, and nuts ofsimilar kind and producing a residue of cellulosic material in suitablecondition for conversion into glucose, consisting in initially reducingthe nuts, each in its entirety, fiber, shell and kernel, to amass ofcomminuted particles, and then extracting the oil from this mass.
